To all whom it may concern: 7

Be it known that I, HENRY F. SAWTELLE, a citizen oi the United States ofAmerica, and a resident of Lcominster, in the county of Worcester and'State of Massachusetts, have invented certain new and usefulImprovements in Fire-Extinguishers, of which the following is aspecification.

This invention relates to fire extinguishers and particularly to fireextinguishers which are adapted for use on railway cars or similarvehicles and has for its object the production of an extinguisher whichmay be secured to the frame of the vehicle and be accessible for useafter an accident has occurred in whatever position the car may be in. i

The invention consists in certain novel features of construction andarrangement of parts which will be readily understood by reference tothe description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a side elevation of a portion of acar showing the preferred location of the fire extinguisher embodyingthe features of this invention. Fig. 2 represents a transverse sectionof the same looking toward the end of the car and showing anextinguisher embodying the features of this invention secured to theunder side of the framework. Fig. 3 represents an elevation, partlyinsection, of the extinguisher, drawn to an enlarged scale. Fig. 4represents a' plan, partly in section, of the same. Fig. 5 represents anend view of the same. Fig. 6 represents a section on line 66' on Fig. 3,looking in the direction of the arrow. Fig. 7 represents a transversesection on line 7-7 on Fig. 3, looking in the direction of the arrow.Fig. 8 represents a section on line 88 on Fig. 5, looking in thedirection of the arrow, and Fig. 9 represents a horizontal section online 99 on Fig. 8.- Fig. 10 represents an enlarged section of a portionof the acid-receptacle breaking device. Fig.- 11 represents a section ofthe acid-receptacle, and Fig. 12 represents a section show ing the meansof securing the longitudinal pipes to the main tank. I

Similar characters designate like the several \figures of the drawings.

In the drawings, 10 represents a. car of any suitable constructionmounted upon any desired truck 11. From the bottom'of the frame 12 ateither side of the car depends the bracket 13 in which is mounted acylindrical tank 14 extending transversely of said car, said tank beingprevented from end movement by means of the flanges 15 abutting saidbrackets 13. Each end of the tank 14 is provided with an extension 16 inwhich is mounted an acid-receptacle 17 which parts throughout ispositioned in said extension by means of a plurality ofinwardly-extending lugs from the inner walls of said extension and acollar 18 threaded to the open end thereof. The receptacle 17, by thesevarious lugs and the collar 13, is held firmly in position and preventedfrom being displaced during the movement of the car to which the fireextinguisher may be attached. The receptacle 17 is preferably of glassand is provided with an annular channel 19 cut into the peripherythereof near one end for the purpose of weakening the receptacle so thatit will break at this point when an accident occurs to permit the acidto escape into the interior of the tank 14 and mix with the contentsthereof to create sufficient gas therein to force out the liquidscontained within as will be hereinafter described.

Secured to the extension 16 are a plurality of bosses 20 in which ismounted a pointed pin 21 tl1e point of which engages with the bottom ofthe annular groove 19 in the receptacle 17. Said pin 21 is preventedfrom displacement by means of the perforated plate 22 secured to theouter end of said boss 20, the per foration s 23 therein providing aready means whereby a. nail or other member may engage with the rear endof said pointed pin 21 and be driven thereby into.

contact with the acid-receptacle 17 for the purpose of effecting abreakage thereof. I side the heads of the tank 14 at each end is anannular pipe 24 connected by a plurality of pipes 25 'which'aresupported midway of their length by the Ts 26 secured to the casing 14by means of the threaded shank 27 and nuts 28. These pipes 24 and 25 areall connected so that the contents of the tank are free to move freelytherethrough and one of the Ts 26 is provided with an additional branch29 to which is connected 2. tube 30 the opposite end of which isprovided with a hollow bulb-shaped weighted strainer end 31. Thisstrainer end 31 is adapted to seek the bottom of the tank 14 in whateverposition it may take and in ordento pro vide for this the tube 30 iseither made flexible throughout its length or at that point where it isconnected to the branch 29.

Each of the annular pipes 24 is provided with a plurality of outwardlyextending bosses 32 to which is breaded the valve casing 33 the innerend of which is provided with a perforated conical end 34 in which isnormally seated a valve 35 held to its seat by the spring 36.

The outer end of the member 33 has threaded thereto a member 37 byturning which the valve 35 may be removed from its seat to permit thepassage of'the liquid contained in the tank 14 through the perforatedend 34 and through the discharge outlet 38, said discharge outletextending through a threaded boss 39 to which any ordinary hose may beconnected, this hose being normally kept in a compartment 40 secured tothe under side of the frame of the car adjacent to the tank 14. Thisreceptacle 40 is pgovided with a door on either side of the car so thatthe hose is accessible in whatever position the car may be in after anaccident has occurred.

said tank 3 8 owing to the action of the valve 35 35 hasbeen opened bythe operation of the threaded in the outer face of each extension 15 ismounted a gage 41 which indicates the pressure within the tank 14 at alltimes.

In the operation of the device the tanks are preferably the perforationsin the weighted strainer end 31 and 15'- through the pipe or tube 30into the pipes 25 from which they will pass through the valve casing 32and out through the outlet 38 into the hose which may be coupledthereto. It is obvious, however, that this operation does not commenceuntil the receptacle 17 containing the acids has been broken either bymeans of the jar due to the accidentor by having the receptaclepositively broken by means of the breakingpin 21 being driven sharplyinto contact with the weakened portion 190i said receptacle. Even whenthis occurs the liquid will not be able to escape through the dischargeoutlet. until this valve member 37 thereon.

The tank is designed with the acid-receptacles at either end so thatnomatter in what position the car may be after an accident has occurred atleast one end thereof will be accessible so that a passenger or trainhand could break the receptacle more conveniently and allow the contentsto mix with the contents of the tank v by such accident.

for the purpose of producing the fire extinguishing mix ture. In asimilar manner the outlet valve casings are situated so that a hose maybe easily coupled to one or the other of these discharge nozzles 39 nomatter in what position the car may be. It is also obvious that theflexible tube' 30 is of such a length that the weighted strainer endthereof seeking its lowest level will reach the bottom of the tankwhatever may be its position so that the liquid contained withinsaidtank will be iorced therethrough by the gases collected therein andthese liquids will be forced through the pipes onto the fire toextinguish the same. i

This makes a very desirable lire extinguisher, par

ticularly adapted for use in conna ction with moving vehicles andespecially railway cars, it being obvious that irom an inspection oi thedrawings and from the description herein given that no matter what maybe the position of the vehicle'after an accident has occurred a hose maybe readily coupled to at least one of its coupling nozzles and the valvereadily operated to permit the contents to flow through its outlet intothe hose for use in extinguishing any fire which may have been ignitedIt is obvious that provision is also made whereby the acid-receptacle isfirmly positioned so that it is unliable to breakage during the ordinarymovement of the vehicle to whichsaid extinguisher may be attached, whileit may be readily broken by the jar caused by the accident to place thefire extinguisher in commission. If such breakage does not occur fromthe jar caused by the accident provision is made whereby the receptaclemay be positivelybroken by a train hand or other person with thesimplest implements at hand.

It is believed that from the foregoing the operation of the inventionand its many advantages will be fully apparent without furtherdescription.
